Anthropic expanded Claude's voice mode to its Opus and Sonnet models on July 23, 2026, an update that includes support for Latin American Spanish and integration with Gmail, Slack, Canva, and Notion, The Verge reported. The feature, previously limited to the Haiku model, now enables voice interactions with the company's highest-reasoning-capability models, marking the first time voice mode has moved beyond Anthropic's lightest model.
Voice mode debuted in May 2025 exclusively with Haiku, a fast model with shallower analytical depth. With the expansion to Opus and Sonnet, Anthropic is responding to a shift in usage patterns: a growing number of professionals are turning to voice not for quick queries, but for complex tasks such as drafting proposals, adjusting calendars, or preparing presentations, according to TechCrunch. The inclusion of Spanish, alongside eight other languages including French, German, Hindi, Portuguese, Japanese, and Korean, broadens access for Latin and Mexican-American communities in North America, where generative AI productivity tools are seeing accelerating adoption among professionals and bilingual small businesses.
The update enables voice mode to connect with third-party applications. A user can ask Claude to review their Gmail inbox, update a meeting in Google Calendar, or draft a document in Notion, all by voice. Free-plan users are limited to the Haiku model and a single connected application. The feature also allows switching between models within the same conversation: starting with Haiku for a quick query and switching to Opus for deeper analysis. The company highlighted use cases such as receiving feedback on communication style, rehearsing client presentations, and generating ideas for market research. According to The Verge, Anthropic did not modify the voice model in this update; improvements to natural conversation, such as handling interruptions, are reserved for a later stage.
The beta version has been available across all platforms since July 23. Unlike other voice assistants on the market, Claude's ability to connect with Gmail, Slack, Canva, and Notion and execute tasks by voice places it in a distinct category within the professional productivity segment. Anthropic has not announced dates for the next phase of conversational improvements.
